Watchful Waiting Without an Antibiotic: A Plan for CT-Confirmed Uncomplicated Diverticulitis in a 47-Year-Old

Unit 4 Watchful Waiting Plan
[Instructor Name]
[Date]
The patient is a composite; orders, values and the review interval are bracketed composite values.
Decision
Observation without antibiotics, with a phone review at 48 hours and a clinic review on day [7], for CT-confirmed uncomplicated left-sided diverticulitis in a well, immunocompetent adult who can drink and can return.
Case
Mr. [B.], 47, a warehouse shift supervisor, has had two days of constant left lower abdominal pain, mild nausea and a reduced appetite. Temperature [37.7] C, heart rate [88], blood pressure [132/80]. Tender in the left lower quadrant without guarding or rebound. White blood cell count [11,800] per microliter, C-reactive protein [62] mg/L. CT of the abdomen and pelvis from the urgent care center yesterday shows inflammation around a sigmoid diverticulum, with no abscess, no free air, no fistula and no obstruction. He has had no previous episode. He has no diabetes, takes no immune-suppressing medicine and is not pregnant. He is drinking fluids and kept down breakfast. He lives with his wife, has a working phone and a car, and the clinic is twenty minutes away.
Rationale: Three Conditions
Condition 1, the illness often settles without antibiotics. Two randomized trials found that patients with CT-confirmed uncomplicated diverticulitis managed without antibiotics recovered as well as those given them. In the AVOD trial, antibiotics neither sped recovery nor prevented complications or recurrence (Chabok et al., 2012). In the DIABOLO trial, observation did not prolong recovery and was associated with a shorter hospital stay (Daniels et al., 2017). Uncomplicated diverticulitis is now understood as an inflammatory process in many patients, not always an infection requiring antibiotics. Current guidance suggests managing most such patients without antibiotics initially, with selective use for those at higher risk (Peery et al., 2021; Qaseem et al., 2022).
Condition 2, the case is uncomplicated. The CT shows no abscess, perforation, fistula or obstruction. He is not septic: his temperature is below 38 C, his heart rate is under 100 and his blood pressure is normal. His white count and C-reactive protein are raised modestly, not markedly.
Condition 3, follow-up is dependable. He can drink and keep down food, so he does not need intravenous fluids. He can be reached by phone, has transport, and understands when to return. Guidance reserves antibiotics for patients who are immunocompromised, frail, have significant comorbidities, cannot take fluids, or show signs of systemic infection (Peery et al., 2021). He is none of those.
Why Not an Antibiotic Just in Case
Mr. [B.] asked the obvious question: would it not be safer to take an antibiotic anyway? The honest answer is that the trials looked for exactly that benefit and did not find it, while the harms of a course of antibiotics are real. The usual regimens for diverticulitis cover gut bacteria broadly, often with a fluoroquinolone or amoxicillin-clavulanate, sometimes with metronidazole. They commonly cause nausea, diarrhea and taste disturbance, which can be hard to separate from the illness itself. They carry a risk of Clostridioides difficile infection. Fluoroquinolones carry warnings about tendon injury and other serious effects. And each unnecessary course adds to the pressure that makes resistant organisms more common. An antibiotic taken just in case would not make his recovery faster or more certain, and it could make the next week worse. The plan therefore holds the antibiotic in reserve and names in advance the changes that would release it.
Plan: Symptom Care
1. Clear liquids for [1 to 2] days, then a gradual return to a normal diet as pain eases. Guidance no longer supports long periods of restricted diet (Peery et al., 2021).
2. Pain: [acetaminophen] at a composite schedule. Avoid NSAIDs, which have been associated with complicated diverticular disease, and avoid opioids if possible.
3. Rest from lifting at work for [a few days]; a work note is provided.
Plan: Surveillance
1. Phone review at 48 hours: pain level, temperature, fluid intake and bowel function.
2. Clinic review on day [7]: examination and, if needed, a repeat blood count and C-reactive protein.
3. After recovery: colonoscopy at [6 to 8] weeks if he has not had a high-quality colonoscopy recently, to exclude a cancer that can mimic diverticulitis on CT.
Return Precautions
Bring the review forward, call the clinic the same day, if:
1. Pain is getting worse rather than better after 48 hours.
2. Temperature rises to 38.0 C or above.
3. He cannot keep fluids down.
Seek emergency care now if:
1. Pain becomes severe or spreads across the abdomen.
2. He has a high fever with shaking chills.
3. He feels faint, confused or very unwell.
4. He cannot pass urine, or passes gas or stool from the urinary tract.
What Would Change the Plan
Antibiotics would start if he developed fever, a rising white count, worsening pain, or intolerance of fluids. Admission and repeat imaging would follow if pain or fever suggested an abscess or perforation.
Agreement
Mr. [B.] and his wife heard the options, including an immediate antibiotic, and chose observation. They left with a written copy of this plan and the clinic's direct number.

How this NU566 Unit 4 example is structured
The document is built as a set of conditions rather than a narrative. It opens with the decision stated in one line, observation with a defined review point, so the reader knows the conclusion before the justification. The justification then tests three conditions in turn: the condition often settles without antibiotics, the scan shows no abscess, perforation or other complication, and the patient can be contacted, can drink and can come back. Each is answered with findings from the case. The plan section separates symptomatic care from surveillance and gives the review as a count of days rather than a vague soon. Return precautions are split into two tiers, changes that bring the review forward and changes that require same-day or emergency care. A closing line records that the patient agreed to the plan and left with a written copy.

A first watchful waiting plan is written without charge to those materials and delivered within 24-48h, stating its review date, testing each condition for waiting against the case, and listing two tiers of return precautions in plain words.

NU566 Unit 4 questions, answered
Does a watchful waiting plan need a guideline citation?
Almost always. The plan is defensible only if waiting is an accepted option for this condition, and a guideline is the clearest evidence of that. Cite the specific recommendation that permits observation and note any condition it attaches, such as assured follow-up. A general statement that many infections clear on their own will not carry the plan.
What review interval suits a watchful waiting plan?
Long enough for the expected improvement to show and short enough that a worsening course is caught early. For many self-limiting conditions the relevant guideline suggests a window, and the plan should use it. State the interval as a number of days, give the date if the case provides one, and explain why that length fits this condition.
What if the patient wants an antibiotic anyway?
Record the conversation. A plan can acknowledge the preference, explain the reasoning for observation, and document the outcome, whether the patient agreed or a different plan was chosen. Some sections accept a delayed prescription with clear instructions. What graders look for is evidence that the decision was discussed, not that the patient was overruled.
