HIV/AIDS Advanced Clinical Guide
for GCC Nurses

In-depth coverage of ART management, disease staging, opportunistic infection protocols, special populations, and the unique legal and epidemiological context of HIV care in the Gulf.

HIV is a retrovirus that attacks CD4+ T-lymphocytes. Without treatment, progressive immunodeficiency leads to AIDS-defining illnesses. Understanding staging guides treatment initiation and OI prophylaxis decisions.
WHO Clinical Staging
Stage I — Asymptomatic

Asymptomatic HIV infection. Persistent generalised lymphadenopathy (PGL). Normal activity. CD4 typically >500 cells/mm³.

Stage II — Mild Symptoms

Minor mucocutaneous manifestations: seborrhoeic dermatitis, prurigo, fungal nail infections, recurrent oral ulcerations, angular cheilitis. Herpes zoster within past 5 years. Recurrent upper respiratory tract infections. Weight loss <10% body weight.

Stage III — Advanced Symptoms

Unexplained weight loss >10% body weight. Chronic unexplained diarrhoea >1 month. Prolonged unexplained fever >1 month. Oral candidiasis (thrush) or oral hairy leukoplakia. Pulmonary tuberculosis (current). Severe bacterial infections (pneumonia, meningitis, septicaemia). Acute necrotising stomatitis/gingivitis. Unexplained anaemia (<8 g/dL), neutropaenia, or thrombocytopaenia.

Stage IV — AIDS-Defining Illnesses

PCP: Pneumocystis jirovecii pneumonia. CMV: Cytomegalovirus retinitis or other organ involvement. Toxoplasmosis: Cerebral toxoplasmosis. MAC: Disseminated Mycobacterium avium complex. Cryptococcosis: Cryptococcal meningitis or disseminated infection. Kaposi's Sarcoma: Any site. Wasting syndrome: >10% weight loss + chronic diarrhoea or unexplained fever. HIV-related encephalopathy, CNS lymphoma, disseminated endemic mycoses, recurrent Salmonella bacteraemia.

Viral Load Monitoring
📈

Viral Load Targets

  • Undetectable (<50 copies/mL): Treatment success — viral suppression achieved
  • 50–999 copies/mL: Low-level viraemia — assess adherence; repeat in 3 months
  • 1,000–9,999 copies/mL: Virological failure — resistance testing; adherence support
  • >10,000 copies/mL: Significant failure — urgent review; regimen change likely needed
U=U (Undetectable = Untransmittable): Patients with sustained undetectable VL cannot sexually transmit HIV. This message reduces stigma and improves treatment motivation. Nurses have a key role in communicating this.
📋

Monitoring Schedule

  • Baseline VL at diagnosis
  • Repeat VL at ART initiation
  • VL at 3 months after ART start
  • VL at 6 months after ART start
  • 6-monthly VL once suppressed
  • CD4 at baseline; repeat if VL unsuppressed or clinical concern
  • Resistance testing before regimen change
Primary HIV Infection — Acute Retroviral Syndrome

Acute Retroviral Syndrome (ARS)

Occurs 2–4 weeks post-exposure in 50–90% of individuals. High VL, rapid CD4 decline, and high transmissibility during this window period.

COMMON SYMPTOMS

  • Fever (96%)
  • Lymphadenopathy (74%)
  • Pharyngitis (70%)
  • Erythematous maculopapular rash (70%)
  • Myalgia/arthralgia (54%)
  • Oral ulcers/thrush (32%)
  • Night sweats, headache, diarrhoea

DIAGNOSTIC NOTE

HIV antibody tests may be negative during ARS (window period). Order HIV RNA/PCR or 4th-generation Ag/Ab combination test. Diagnose early — immediate ART reduces transmission and reservoir size.

📊 CD4 / Viral Load Monitoring Tracker

Enter the patient's current values to receive a treatment response assessment, OI risk level, and prophylaxis checklist.

WHO 2021 recommends ART for ALL people living with HIV, regardless of CD4 count. Early initiation reduces transmission, AIDS complications, and non-AIDS morbidity. Same-day or rapid ART start is preferred when clinically safe.
ART Drug Classes
💊

NRTIs — Nucleoside Reverse Transcriptase Inhibitors

BACKBONE of all regimens (2 NRTIs + 1 third agent)

DrugKey Points
TDF Tenofovir DFPreferred backbone; active against HBV co-infection; monitor renal function/phosphate
FTC EmtricitabinePaired with TDF (Truvada/Descovy); active against HBV
3TC LamivudineAlternative to FTC; also HBV-active; well tolerated
ABC AbacavirHLA-B*5701 testing BEFORE starting — hypersensitivity reaction risk (potentially fatal)
HBV Co-infection: NEVER stop TDF/FTC or 3TC in HBV+HIV co-infected patients without an alternative HBV-active agent — risk of HBV flare and hepatic decompensation.
💊

NNRTIs — Non-Nucleoside Reverse Transcriptase Inhibitors

DrugKey Points
EFV EfavirenzCNS side effects (vivid dreams, dizziness, depression) — take at bedtime. AVOID in 1st trimester pregnancy — neural tube defect risk (neuroteratogenic)
RPV RilpivirineMust take with a full meal (≥390 kcal); avoid with PPIs; active against EFV-resistant strains
DOR DoravirineNewer NNRTI; fewer CNS effects; can be taken without food
💊

PIs — Protease Inhibitors

Require pharmacokinetic boosting with ritonavir (RTV) or cobicistat (COBI)

DrugKey Points
DRV/r Darunavir/ritonavirPreferred PI; high genetic barrier to resistance; GI side effects
LPV/r Lopinavir/ritonavirUsed in resource-limited settings; significant GI side effects; lipodystrophy
PI Class Effects: Dyslipidaemia, lipodystrophy (fat redistribution — buffalo hump, lipoatrophy), GI intolerance, hepatotoxicity. Monitor lipids, LFTs, glucose. Significant drug-drug interactions (CYP3A4).
💊

INSTIs — Integrase Strand Transfer Inhibitors

Gold standard first-line agents — high potency, high barrier to resistance

DrugKey Points
DTG DolutegravirWHO-preferred first-line. Pregnancy safe (preferred). High barrier. Insomnia/weight gain reported. Avoid with antacids/cations ±2h.
BIC BictegravirIn Biktarvy (BIC/FTC/TAF); once daily; no food requirement; high barrier

Monthly or every-2-month IM injections. For virologically suppressed patients. Eliminates daily pill burden. Must take with meal. Not if CD4<200 or VL>50.
CAB LARPV LA
ART in Pregnancy

Pregnancy-Specific ART Considerations

  • DTG is the preferred INSTI in pregnancy (all trimesters, including 1st trimester per WHO 2021 updated guidance — neural tube defect risk very low)
  • EFV avoid in 1st trimester — historical neuroteratogenicity concern
  • Continue TDF + FTC/3TC backbone (renal function monitoring)
  • ART reduces vertical transmission to <1% if VL undetectable
  • C-section if VL >1,000 copies/mL near delivery
  • Infant ARV prophylaxis: Nevirapine (NVP) syrup × 6 weeks
  • Early infant diagnosis: PCR at 4–6 weeks of age
  • In GCC: formula feeding generally safe (safe water access); breastfeeding decisions require individualised counselling
  • Monitor mother: LFTs, renal function, FBC throughout
  • Maternal VL at delivery: target undetectable
Opportunistic infections (OIs) are the leading cause of morbidity and mortality in people with HIV. Primary prophylaxis prevents first OI episodes; secondary prophylaxis prevents recurrence. All indications are CD4-threshold driven.
OI Prophylaxis & Treatment Summary
OIProphylaxis IndicationProphylaxis AgentTreatmentStop Prophylaxis When
PCP CD4 <200 cells/mm³ Co-trimoxazole 480mg OD Co-trimoxazole 960mg TDS × 21 days + steroids if severe (PaO₂ <70 mmHg) CD4 >200 on ART × 3 months
Toxoplasma CD4 <100 + seropositive IgG Co-trimoxazole 960mg OD Pyrimethamine + Sulfadiazine + Folinic acid × 6 weeks (acute); then secondary prophylaxis CD4 >200 × 6 months on ART
Cryptococcal Meningitis Cryptococcal Ag screen if CD4 <100 Fluconazole 200mg OD if CrAg+ Severe: Liposomal AmB × 7d + Flucytosine then Fluconazole 400mg OD × 8 weeks → 200mg OD maintenance CD4 >200 × 6 months on ART

TB/HIV Co-infection — Key Clinical Considerations
🚀

TB-ART Drug Interactions

Rifampicin is a potent CYP450 inducer — it dramatically reduces serum levels of most ART drugs.
  • EFV is compatible with rifampicin (EFV dose adjustment if <60kg)
  • DTG 50mg BD (double dose) is acceptable with rifampicin
  • PIs are NOT recommended with rifampicin — use rifabutin as TB drug substitute
  • RAL 800mg BD may be used with rifampicin
  • Never use rifampicin with ritonavir-boosted PIs
🚫

IRIS — Immune Reconstitution Inflammatory Syndrome

IRIS occurs when ART restores immunity and causes a paradoxical inflammatory response to existing or subclinical infections.

  • Paradoxical IRIS: Worsening of known OI after ART initiation
  • Unmasking IRIS: New OI presentation after ART initiation
  • Risk: Low CD4 at ART start, early ART initiation in OI setting
  • Common triggers: TB, CMV, Cryptococcus, MAC
  • Management: Continue ART (usually); NSAIDs/steroids for moderate-severe; treat underlying OI
  • Cryptococcal IRIS: High mortality — delay ART 4–6 weeks post-fluconazole
Cryptococcal Meningitis — Nursing Management
💭

Raised Intracranial Pressure (ICP) Management

ICP elevation is the major cause of early mortality in cryptococcal meningitis. Therapeutic LPs are essential.

  • Measure opening pressure on ALL LPs in cryptococcal meningitis
  • Remove CSF to normalise pressure if opening pressure >25 cmH₂O
  • Daily therapeutic LPs until pressure normalised
  • Do NOT use acetazolamide or steroids for ICP in Crypto
  • Monitor for herniation signs: drowsiness, cranial nerve palsies, papilloedema

NURSING OBSERVATIONS

  • GCS and focal neurological signs hourly initially
  • Strict headache score monitoring
  • Vision changes — urgent ophthalmology
  • Post-LP monitoring: BP, HR, positioning
  • Fluconazole blood levels if poor response
HIV in Pregnancy

Prevention of Vertical Transmission (PMTCT)

Vertical transmission risk: 15–45% without intervention → <1% with optimal ART + obstetric management. Four key components: ART, mode of delivery, feeding choice, infant prophylaxis.
  • Initiate ART immediately regardless of CD4 or gestation
  • Target: undetectable VL by delivery
  • C-section if VL >1,000 copies/mL at 38 weeks
  • In GCC: formula feeding recommended where safe water accessible (reduces transmission to near zero)
  • Infant NVP prophylaxis × 6 weeks
  • HIV PCR at 4–6 weeks of age (antibody testing not valid until 18 months)
GCC Immigration Note: HIV-positive pregnant women (especially expatriates) may face deportation. This creates barriers to antenatal disclosure and treatment. Nurses must maintain strict confidentiality and provide non-judgemental care regardless of immigration status.
HIV in Women

Sex-Specific Considerations

  • Biologically more susceptible to HIV than men (mucosal surface area, microtrauma)
  • Cervical cancer screening: 6-monthly Pap smear if CD4 <200
  • HPV vaccination recommended (up to age 45 in HIV+)
  • Menstrual irregularities common — monitor for amenorrhoea (OI, weight loss, ART effects)
  • Osteoporosis risk — TDF + low oestrogen combined
  • Contraception counselling (interactions with ART and hormonal methods)
  • EFV reduces ethinyl oestradiol levels by 37% — non-hormonal or alternative contraception
  • Rilpivirine increases ethinyl oestradiol — minor interaction, monitorable
  • DTG: no significant contraceptive interactions
  • STI screening 3-monthly (chlamydia, gonorrhoea, syphilis)
  • DEXA scan baseline if on TDF or corticosteroids
HIV in Older Adults
💰

Ageing with HIV — Accelerated Ageing Syndrome

People living with HIV on ART live into older age but experience age-related comorbidities 10–15 years earlier than HIV-negative peers due to chronic immune activation and ART toxicity.

ACCELERATED AGE-RELATED CONDITIONS

  • Cardiovascular disease (early atherosclerosis — HIV inflammation + PI dyslipidaemia)
  • Bone density loss and fractures (TDF, chronic inflammation, low vitamin D)
  • Neurocognitive impairment (HIV-associated neurocognitive disorder — HAND)
  • Renal disease (TDF nephrotoxicity + HIV nephropathy)
  • Non-AIDS malignancies (anal, lung, liver cancers)
  • Frailty and sarcopenia

NURSING MANAGEMENT

  • Polypharmacy review — ART + ≥5 other medications
  • Falls risk assessment and DEXA scan
  • Annual cardiovascular risk score (Framingham or D:A:D)
  • Annual cognitive screening (MoCA or MMSE)
  • Annual renal function: eGFR, phosphate, creatinine
  • Cancer screening aligned with population guidelines
  • Depression and loneliness screening
HIV in Healthcare Workers
🛠

Occupational Exposure & GCC Disclosure

  • Occupational exposure risk: needlestick ≈0.3%; mucous membrane ≈0.09%
  • Report ALL occupational exposures immediately to Occupational Health
  • Post-exposure prophylaxis (PEP): start within 1–2 hours; up to 72 hours maximum
  • PEP regimen: TDF + FTC + DTG × 28 days
  • Baseline and 6-week/3-month HIV serology
GCC Context: Healthcare workers living with HIV have faced job loss and deportation in GCC countries. Disclosure obligations vary by country. Nurses must be aware that HIV-positive HCWs face significant professional and legal vulnerability. Advocacy and confidentiality are essential.
Critical threshold: >95% adherence is required for consistent viral suppression. Missing just 5% of doses can lead to detectable viraemia and, over time, drug resistance. Resistance accumulates silently — by the time it is detected, multiple mutations may have developed.
Adherence Barriers & Strategies

Common Adherence Barriers

  • Pill burden: Multiple tablets, complex schedules
  • Side effects: Nausea, diarrhoea, fatigue, CNS effects (EFV)
  • Stigma: Fear of discovery by family/employer
  • Depression & mental health: Depression reduces adherence by 3-fold
  • Substance use: Alcohol, khat, opioids impair adherence
  • Forgetfulness: Irregular lifestyle, shift work
  • Cost & access: Especially expatriates in GCC without health insurance
  • Denial: Asymptomatic patients may not feel the need for treatment

Evidence-Based Adherence Interventions

  • Phone/app medication reminders (Medisafe, Apple Health)
  • Blister packs and dose-tracking pillboxes
  • Designated treatment supporters (peer counsellors)
  • Motivational interviewing by nurse prescribers
  • Peer support groups (discreet/anonymous where available in GCC)
  • Simplify regimen: switch to once-daily single-tablet if eligible
  • Long-acting injectables (CAB+RPV) for patients with pill-taking challenges
  • Mental health co-management: treat depression/anxiety alongside HIV
  • Patient education — reinforce U=U message as treatment motivation

Treatment as Prevention (TasP)
🌐

U=U — Undetectable = Untransmittable

The PARTNER, HPTN 052, and Opposites Attract studies collectively demonstrated ZERO onward HIV transmissions from partners with undetectable viral load (<200 copies/mL) during condomless sex. This is the most powerful treatment adherence message available.

NURSE'S ROLE IN U=U

  • Communicate U=U clearly at every relevant consultation
  • Document viral load achievement and use it as positive reinforcement
  • Address misconceptions — many patients (and nurses) are unaware of U=U
  • Reduce stigma in practice — U=U challenges the "danger" narrative
  • In GCC context: U=U may be culturally sensitive but remains medically valid
PrEP (Pre-Exposure Prophylaxis): TDF/FTC daily for HIV-negative high-risk individuals. Highly effective (>99% adherent use). Limited availability in GCC but available in Dubai (DHA) and some Saudi hospitals. Nurses can provide PrEP education and counselling.

📋 ART Adherence Risk Screener

A 5-question clinical screening tool. Answers generate an adherence risk level with targeted nursing support strategies.

1. How often do you forget to take your HIV medications?

2. Are you currently experiencing significant side effects from your ART?

3. Are you worried that someone will discover your HIV status if they see you taking medication?

4. Do you currently have depression, anxiety, or use alcohol/substances that affect your daily routine?

5. How confident are you that you can take your HIV medication every day for the long term?

Critical GCC Context: HIV care in Gulf countries is profoundly shaped by legal criminalisation, deportation policies, and deep cultural stigma. Nurses must understand this context to provide safe, non-judgemental, confidential care. Failing to protect confidentiality may directly harm patients.

Epidemic Profile

KEY POPULATIONS

  • Sex workers (both male and female)
  • Men who have sex with men (MSM)
  • People who inject drugs (PWID)
  • Migrant workers (from high-prevalence countries)
  • Prisoners (limited data)

STRUCTURAL FACTORS

  • Mandatory HIV testing on employment/visa entry for most expatriates
  • Positive result → deportation without treatment initiation in most GCC states
  • Creates massive testing avoidance — true prevalence likely significantly underestimated
  • Religious and social norms: homosexuality and sex work are criminalised
  • No harm reduction programmes (needle exchange, opioid substitution) in most GCC states

Nursing Ethical Practice in GCC HIV Care
🔒

Confidentiality — Non-Negotiable

  • HIV status is strictly protected health information under all GCC health regulations
  • Do NOT disclose HIV status to employers, immigration authorities, or family without explicit informed consent
  • Document HIV status only in clinical records with restricted access
  • Informed consent for HIV testing — voluntary (except mandatory employment screening)
  • Provide pre- and post-test counselling for all diagnostic tests
  • Be aware: inadvertent disclosure (leaving results visible, discussing in ward) has led to patient deportation and job loss

Non-Judgmental Approach to Key Populations

Nurses may care for patients whose behaviours are illegal in the GCC (MSM, sex workers, PWID). The nurse's role is healthcare provision, not moral judgement or legal enforcement.

  • Provide identical quality of care regardless of mode of HIV acquisition
  • Do not ask about sexual orientation unless clinically indicated
  • Harm reduction counselling remains appropriate even where programmes are illegal
  • Recognise patient fear of disclosure — acknowledge it, address it, protect against it
  • Refer to mental health services — high rates of depression/suicidality in HIV+ patients in stigmatising environments
Treatment Interruption Risk — Expatriates

Interrupted ART — Clinical Consequences

Expatriates in GCC may be deported mid-treatment, or may lose employment and healthcare access. Treatment interruption leads to rapid VL rebound (within 1–2 weeks), CD4 decline, and resistance risk if restarted after subtherapeutic levels.

Nursing Action: When an HIV+ expatriate patient is at risk of deportation or loss of healthcare access, work with social work and infectious disease teams to ensure: (1) medication supply to cover transition; (2) onward referral letter for receiving country; (3) documentation of current regimen and resistance history; (4) contact details for local HIV services in home country.

0 / 10
Questions answered correctly
1. A patient with HIV has a CD4 count of 160 cells/mm³. Which opportunistic infection prophylaxis is MOST urgently indicated?
A Azithromycin 1200mg weekly
B Co-trimoxazole 480mg once daily
C Fluconazole 200mg once daily
D Isoniazid 300mg once daily
Co-trimoxazole prophylaxis is indicated when CD4 <200 cells/mm³ to prevent PCP (and Toxoplasma). Azithromycin is for MAC prophylaxis (CD4 <50). Fluconazole is for cryptococcal disease. Isoniazid is for latent TB prevention.
2. A pregnant woman with HIV is 8 weeks gestation. Which antiretroviral regimen is currently WHO-preferred?
A TDF + FTC + Efavirenz 600mg
B AZT + 3TC + Lopinavir/ritonavir
C TDF + FTC + Dolutegravir
D ABC + 3TC + Raltegravir
WHO 2021 recommends TDF + FTC + DTG as the preferred regimen in pregnancy including the first trimester. Efavirenz was historically avoided in early pregnancy due to neural tube defect concerns, though updated evidence has significantly revised this risk. Dolutegravir is now considered safe and preferred.
3. A patient with cryptococcal meningitis and HIV has an opening CSF pressure of 32 cmH₂O. What is the PRIORITY nursing/clinical action?
A Administer IV dexamethasone immediately
B Start acetazolamide to reduce ICP
C Perform therapeutic lumbar puncture to normalise pressure
D Initiate ART immediately to restore immunity
Therapeutic LP is the cornerstone of raised ICP management in cryptococcal meningitis. Remove CSF to normalise pressure (<20 cmH₂O). Steroids and acetazolamide are NOT recommended in crypto ICP and may be harmful. ART should be delayed 4–6 weeks to avoid IRIS.
4. A patient is started on rifampicin for TB while taking dolutegravir. What is the correct ART adjustment?
A Stop dolutegravir and start lopinavir/ritonavir
B Increase dolutegravir to 50mg twice daily
C Keep dolutegravir at 50mg once daily — no change needed
D Switch to tenofovir alafenamide monotherapy
Rifampicin induces CYP3A4 and reduces dolutegravir levels by ~57%. The correct adjustment is to increase DTG to 50mg BD (twice daily). PIs must NOT be used with rifampicin due to critically reduced PI levels. Rifabutin is an alternative TB drug that has fewer interactions if PI is essential.
5. What does U=U mean in clinical HIV management?
A Undisclosed = Untreatable
B Undertreated = Unsafe
C Undetectable = Untransmittable
D Undetectable = Uncurable
U=U stands for Undetectable = Untransmittable. Evidence from PARTNER (2019), HPTN 052, and Opposites Attract studies shows zero sexual transmissions from partners with sustained undetectable viral load (<200 copies/mL). This message is a key adherence motivator and stigma-reduction tool.
6. A patient on tenofovir disoproxil fumarate (TDF)-based ART develops a gradual rise in serum creatinine and hypophosphataemia. What is the most likely diagnosis and correct action?
A HIV nephropathy — no ART change needed
B Contrast nephropathy — hydrate patient
C TDF-induced proximal tubular toxicity (Fanconi syndrome) — switch to TAF
D Cotrimoxazole nephrotoxicity — stop prophylaxis
TDF can cause proximal renal tubular toxicity presenting with raised creatinine, hypophosphataemia, glycosuria, and proteinuria (Fanconi-like syndrome). The appropriate action is to switch from TDF to TAF (tenofovir alafenamide), which has a much lower renal and bone toxicity profile.
7. A patient presents with fever, rash, pharyngitis, and lymphadenopathy 3 weeks after a potential HIV exposure. The HIV antibody test returns negative. What is the CORRECT interpretation?
A HIV infection is definitively excluded
B Patient has a viral URI — no further action needed
C Possible acute retroviral syndrome — order HIV RNA/PCR or 4th-generation Ag/Ab test
D Patient requires repeat antibody test in 2 years
This is a classic presentation of Acute Retroviral Syndrome (ARS). The HIV antibody test may be negative during the window period (2–4 weeks). A 4th-generation combination Ag/Ab test or HIV RNA PCR must be ordered to detect acute infection. Early diagnosis allows immediate ART initiation and prevents transmission.
8. Before prescribing abacavir (ABC), what is the mandatory screening test?
A G6PD deficiency screening
B CYP2D6 genotyping
C HLA-B*5701 genotyping
D Cryptococcal antigen test
HLA-B*5701 testing is mandatory before starting abacavir. Carriers of HLA-B*5701 have up to 55–60% risk of severe, potentially fatal hypersensitivity reaction (ABC HSR) characterised by fever, rash, and multi-organ involvement. If positive, ABC must NEVER be prescribed. If negative, ABC can be used safely.
9. An HIV-positive expatriate nurse in a GCC country discloses their status to you privately. What is your PRIMARY obligation?
A Report to the nursing manager for infection control purposes
B Notify the hospital occupational health department immediately
C Maintain strict confidentiality and provide support, referring to HIV care services
D Inform immigration authorities as required by law
Confidentiality is the primary obligation. HIV status is protected health information. Unauthorised disclosure could result in the nurse's deportation, job loss, and psychological harm. There is no automatic requirement to report to managers, immigration, or occupational health without consent. Provide compassionate support and referral to HIV services. Legal obligations vary by jurisdiction — seek guidance from ethics/legal teams if genuinely uncertain.
10. At what CD4 count should MAC (Mycobacterium avium complex) prophylaxis with azithromycin be initiated?
A CD4 <200 cells/mm³
B CD4 <100 cells/mm³
C CD4 <50 cells/mm³
D CD4 <350 cells/mm³
MAC prophylaxis with azithromycin 1200mg weekly is indicated when CD4 falls below 50 cells/mm³. This is the most profound level of immunosuppression. At this CD4 level, CMV retinitis surveillance (ophthalmology) is also essential. PCP prophylaxis begins at CD4 <200, and Toxoplasma at CD4 <100 in seropositive patients.
